Happy Tuesday all! Another gorgeous but WINDY day ahead with unseasonable warmth & 35 mph gusts whisking the dense morning fog which has formed in some west suburbs and across northern IN into MI away. But temps dive overnight as a shot of the coldest air of the season sweeps in off a mass of frigid air which has been building over western & north North America. Temps at the heart of this air mass failed to get above 0 yesterday from portions of Canada's Yukon & Nunavut and Northwest Territories west into interior Alaska. Morning lows were as cold as -33 in the northern Yukon! NOTHING like that's headed this way--but readings will dip into the 20s inland overnight and struggle into the low 40s Wed and to near 40 Thu--the coldest temps here in 7 months. Ahead of the chill, readings head into the 60s today (Tuesday)--a level more typical of mid October than mid-November! November is posting a near 5-degree surplus when compared to its long term average. Our climate guru Rich Koeneman ran stats for us yesterday on late season 60-deg-plus temps and it turns out we have an average of 3 to go--though as many as 13 60s occurred beyond Nov 14 in 1988. Warming's ahead later this week with another shot at 60 possible Saturday as a big autumn storm lifts out of Colorado toward Wisconsin, putting Chicago in its windy warm sector. Check out this 7-day plot of potential snowfall off our in-house MDA database. This forecast is driven by the Weather Service's GFS model. Looks like a snowy late week & early weekend ahead in parts of MN, northern WI & Michigan's UP!

Was not completely sure of where to post this, so this thread was chosen

Here is a little nugget from HM's blog this morning....didn't really want to here this news (but hey what can ya do right)

The GFS and Euro have backed off on the cold in two weeks. Not surprising to see the models are backing off. Just not time for the cold to come on down, despite that fact that a pool of cold weather is developing in Alaska. Eventually, the cold will come down, but not yet.

The Madden-Julian Oscillation has made a large and unexpected change to Phase 1 status. Note Tropical Cyclone 5A near the southwest tip of India. This storm is expected to move north and threaten the coast of Pakistan in about 4 to 6 days. Most of southern Asia is under a warm and dry regime, with the bitter cold Arctic domain encompassing most of Russia and the Central Asian Republics.
